And the like, and the above configuration is basically the same as the conventional one.

The weather strip 2 includes upper and lower jaw pieces 2
A main body portion 21 having a holding frame portion 22 having a substantially U-shaped cross section which connects the 2b and 22b by a connecting portion 22a is formed by a hard synthetic resin such as a hard vinyl chloride resin, and the main body portion 21 is A lip portion 24 made of a soft synthetic resin such as a soft vinyl chloride resin is stretched on the back side. The body 21 and the lip 24 are usually integrally formed by an extrusion molding method, an injection molding method, or the like, but they are separately molded without being integrally molded,
Needless to say, they may be bonded and integrated after that.

And, such a weather strip 2
Is the garnish portion of the door trim body 1 and the holding frame portion 2
2, the upper jaw piece 22b of the holding frame 22 is abutted against the concave step 11 provided on the upper surface side of the garnish, and is positioned and fixed to be integrated. Is extremely high. Further, a metal core plate 23 such as an iron plate or a light metal plate is embedded in the holding frame portion 22 by an insert molding method, and the metal core plate 23 gives a crimping action to the jaw piece portion 22b. It should be noted that the metal core plate 23 is not particularly limited as long as it has a structure that gives a crimping action to at least one jaw piece portion 22b.
As shown in FIG. 5, the tip has an approximately U-shaped frame with an inward protruding portion formed, or the metal core plate 23 is embedded in the main body 21 as shown in FIG. The lower jaw piece 22 is formed in a substantially L-shaped frame having an inward projection.
The one in which the cut-and-raised claw 23a to be embedded in b is formed is used.

When the concave step portion 11 is provided on the upper surface side of the garnish portion as shown in FIG. 1, the weather strip 2 and the door trim main body 1 are flush with each other, and therefore, in terms of handling and appearance. Although it is more preferable, the recessed step portion 11 is provided on the lower surface side of the garnish portion and the jaw piece portion 2 on the lower side of the holding frame portion 2 is provided as shown in FIG.
